dbeacon(1) General Commands Manual dbeacon(1) NAME dbeacon - Distributed IPv4/IPv6 multicast beacon SYNOPSYS dbeacon -a MAIL -b BEACON_ADDR[/PORT] [-i INTFNAME] [-n NAME] [-S [GROUP_ADDR[/PORT]] [-s ADDR] [-d [FILE]] [-I NUMBER] [-W type$url] [-L program] [-C CC] [-4] [-6] [-v] [-P] [-U] [-V] [-F flag] [-O] [-B ADDR] DESCRIPTION dbeacon is a network level management tool aiming at getting various statistics about multicast connectivity. Its first usage is to check out if you can send/receive toward/from an IPv4/IPv6 multicast network. Its second usage is to gather various statistics by using a known mul- ticast ASM group, for example TTL between each multicast peers, loss or jitter figures. Theses statistics are kept internally but can be dumped periodically in a file in xml format for latter processing. Statistics gathering is completetly distributed and rely on the powerful nature of ASM. No server is required, but maybe a http server for accessing the statistics and build an adjacency matrix of the peers. OPTIONS -n NAME, -name NAME The name identifying you on the dbeacon session. If not speci- fied, dbeacon will use the hostname of the running machine. -a MAIL Administrative contact. This is an e-mail used for join you, for example to notify you that something is wrong is your multicast connectivity -i IN, -interface IN Use IN instead of the default interface for multicast. -b BEACON_ADDR/PORT This is the IPv4/IPv6 address of the ASM group used by dbeacon to gather statistics. It can be specified as a DNS name too. -S GROUP_ADDR/PORT Enables SSM reception/sending on optional GROUP_ADDR/PORT -O This option enable SSM data sending in addition to ASM data. It can be used to check if people can reach you via SSM. -B ADDR This allows you to bootstrap from an ADDR that is already in the matrix. This option is useful when you ASM connectivity is bro- ken but SSM connectivity works. -P, -ssmping Enable SSM Ping server capability. -s ADDR Bind to local address. This allow you to specify the multicast source of the packets sent by your beacon. -d FILE Dump periodic reports to dump.xml or specified file. This file may be latter processed by any XML compliant script. On a http server, you can process the dump to create a nice adjacency ma- trix. -I NUMBER, -interval NUMBER Interval between refresh of the dump file. Defaults to 5 secs if not specified -W URL, -website URL Specify a website to announce. -Wm URL, -matrix URL Specify your matrix URL. -Wl URL, -lg URL Specify your looking glass URL. -C CC Specify your two letter Country Code. -L program Launch program after each dump. The first argument will be the dump filename. -F flag Specify a flag to announce. For example to announce that your host is running a ssmpingd deamon, use 'ssmping' as a flag. -4, -ipv4 Force IPv4 usage (Default is IPv6). -6, -ipv6 Force IPv6 usage -v verbose mode (use several for more verbosity) -U Dump periodic bandwidth usage reports to stdout -D, -daemon fork to the background (daemonize) -pidfile FILE Path to the PID file to write to. -syslog Outputs using syslog facility. -c FILE Specifies the configuration file to use. Each of the above com- mand-line parameters can be defined there. -V, -version Outputs version information and leaves BUGS Should be reported to the core developer Hugo Santos <hugo@fivebits.net>. HISTORY dbeacon is a joint work of Hugo Santos, Sebastien Chaumontet and Mick- ael Hoerdt. It has been done in the early days of the m6bone, when no- body knew if the SPTs or RPTs were being used between hosts and also to evaluate the performance and deployment of SSM.
